Replaceable Carbide-Insert End Mills for Manual Milling Machines

Square Cut Style

Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire tool. End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.

Carbide inserts have a wear-resistant titanium-nitride (TiN) coating.

Fly Cutters

Flat-Surface Cut Style

Fly cutters clamp onto tool blanks (sold separately) to machine flat surfaces. As the cutter rotates, the tool blank creates a wide, shallow cut on the face of the workpiece. An alternative to face milling cutters for intermittent and light duty use, these cutters allow you to remove and hand-sharpen the tool blank when it becomes worn.
